Hi,
I have coded personal indicators in probuilder and probacktest longer than 1000 lines, they work fine, and even if I didn’t count the “comments” or empty lines, it’s still order of magnitude 10 times more than 100, I have never encountered any line limit message, only “close to maximum allocated memory” messages when using too many windows and indicators at the same time. So I don’t know if there’s no limit at all for code line numbers, or if there is an existing one I haven’t reached yet, but if there is, I’d say it is certainly not as tiny as 100.
And that’s just version 10.2 PRT complete I’m using, the “PRT premium” version seems to be eve more powerful than the “complete” version according to the description on PRT website.
